1. Subsidies for propagation of native species in Brazil with medicinal potential: Calophyllum brasiliense Cambess
Resumo: Calophyllum brasiliense Cambess. (guanandi) é uma espécie nativa com potencial medicinal e também com expectativa para exploração comercial (madeira) e recuperação de áreas degradadas. As sementes apresentam dormência física e mecânica, exigindo técnicas para superação, e necessitam de conhecimento da morfologia de sementes e plântulas

2. Ensaios para a validação de metodologias para germinação de diásporos de espécies arbóreas do cerrado
A validação de metodologias para teste de germinação de diásporos de espécies florestais exige ampla revisão de literatura e conhecimento sobre os aspectos morfofuncionais de plântulas. Assim, o objetivo foi definir metodologias para teste de germinação de diásporos de espécies florestais de Cerrado, a partir de ensaios para identificação das p

3. Allelopathic interference of Sapindus saponaria root and mature leaf aqueous extracts on diaspore germination and seedling growth of Lactuca sativa and Allium cepa
Sapindus saponaria (soapberry) is a species that presents a great diversity of chemical compounds, such as saponins; however, few studies have examined the allelopathic effect of this species. Therefore, this study provides an evaluation of the allelopathic potential of aqueous extracts of the roots and mature leaves of S. saponaria on the germination of dia

5. Disruption of a DNA Topoisomerase I Gene Affects Morphogenesis in Arabidopsis
The genesis of phyllotaxis, which often is associated with the Fibonacci series of numbers, is an old unsolved puzzle in plant morphogenesis. Here, we show that disruption of an Arabidopsis topoisomerase (topo) I gene named TOP1α affects phyllotaxis and plant architecture. The divergence angles and internode lengths between two successive flowers were more

6. Cytokinesis-Defective Mutants of Arabidopsis1
We have identified mutations in six previously uncharacterized genes of Arabidopsis, named club, bublina, massue, rod, bloated, and bims, that are required for cytokinesis. The mutants are seedling lethal, have morphological abnormalities, and are characterized by cell wall stubs, gapped walls, and multinucleate cells. In these and other respects, the new mu

7. Constitutive Overexpression of Cystathionine γ-Synthase in Arabidopsis Leads to Accumulation of Soluble Methionine and S-Methylmethionine1
The committing step in Met and S-adenosyl-l-Met (SAM) synthesis is catalyzed by cystathionine γ-synthase (CGS). Transgenic Arabidopsis plants overexpressing CGS under control of the cauliflower mosaic virus 35S promoter show increased soluble Met and its metabolite S-methyl-Met, but only at specific stages of development. The highest level of Met and S-meth
